Biogás - CHP Brasil | Geradores a gás

Biogas is a renewable energy source

Biogas is produced by bacteria in the process of decomposition of organic matter, organic matter, agro-industrial waste, animal manure and urban waste, and so on.

Biogas is a renewable biofuel and it has high energy power. It can be used in CHP Brasil's biogas power generators to produce electricity and/or thermal energy.

Biogas can generate electricity for self-consumption, reducing costs with the Energy Distributor, and/or generate financial revenue by exporting electricity in GD, Distributed Generation.

biogás-esquema de produção e aproveitamento energético

1 - Biodigesters

Residues such as animal manure, food waste, sewage, and effluents with high organic load are fed into closed tanks, in the absence of atmospheric air. These tanks can be covered lagoons or more advanced treatment reactors, and are popularly called "biodigesters" in Brazil.

2 - Gases and biofertilizers

Inside these digesters, microorganisms that naturally exist in the waste feed on the organic compounds in the waste. Consequently, part of these compounds is transformed into gases, while another part is transformed into a degraded organic mass, similar to a fertilizer, called biofertilizer.

3 - Methane, CO2, and hydrogen sulfide gas

The gases referred here are a mixture of methane, carbon dioxide gas, and hydrogen sulfide gas, plus water in the form of humidity. Some other gases may also be present in smaller quantities. This mixture of gases is known as biogas, which is an excellent fuel for generating energy, because of methane.

4 - Biogas Treatment

The biogas is processed to remove hydrogen sulfide gas and humidity, since this combination can lead to serious corrosion problems in equipment. Next, the biogas is compressed and injected into a motor-generator set, where it will generate electrical and thermal energy. This energy can supply the demand of a farm, factory, or it can even be sold.

5 - Biometano

Para produzir o Biometano, o biogás passa por um processo de purificação com alta eficiência de forma a eliminar a maioria dos seus constituintes, principalmente o gás carbônico (CO2) e o gás sulfídrico (H2S), com exceção do metano (CH4). Esta purificação tem eleva o poder calorifico do gás, tornando o biometano semelhante ao gás natural.

Biogas Potential in Brazil

In Brazil, the potential for biogas production is very large, given the large participation of the agro industry in the national economy. The number of beef cattle farms, dairy farms, pig farms, poultry farms, fecular factories, and many others, that use biogas for energy generation has been increasing year by year. Another great potential lies in the sanitation sector, mainly in large urban centers, as well as in the food and beverage industries.

CHP Brasil has a high-quality national technology to make the most of the potential of biogas for energy generation. Using high energy efficiency generators, we are able to generate more energy with less biogas. This represents great savings in the plant's monthly electric energy bill. On farms, we are able to produce surplus electricity that can be sold according to the rules of Distributed Generation (DG). In other words, energy savings or revenue with energy, is more competitiveness for your business.

Awite is a German company offering equipment and systems for biogas analysis, desulphurisation and automation.

With over 2,000 installed plants in the World, Awite chose CHP Brasil as its exclusive representative in Brazil, due to the company’s technical competency, ethics and committed team.

The automated desulfurization system injects the exact amount of oxygen into the biodigester, significantly reducing the amount of H2S (hydrogen sulphide). In addition, the automated gas analysis system delivers online monitoring of the composition of the gas leaving the biodigester, thus increasing the reliability of the power generation plant. online da composição do gás que está saindo do biodigestor, aumentando assim a confiabilidade da planta de geração de energia.
